Abstract

La présente invention concerne un résonateur stable pour une cellule de spectroscopie par abaissement d'anneau de cavité et comportant un axe optique. Le résonateur inclut deux prismes rétroréflecteurs à pseudo-incidence brewstérienne, comportant chacun une pluralité de surfaces de réflexion interne totale. Les prismes sont disposés en alignement le long de l'axe optique du résonateur. L'un au moins des deux prismes est susceptible de rotation de façon que les rayons de lumière pénètrent dans une face du prisme et en ressortent sous un angle correspondant sensiblement sous l'angle de pseudo-incidence brewstérienne par rapport à l'axe perpendiculaire à la surface du prisme. Ce dispositif permet de conserver l'alignement entre les prismes et permet l'accord du résonateur. L'une des surfaces de réflexion interne totale de l'un au moins des prismes peut être une surface incurvée, en l'occurrence soit une surface incurvée par meulage, soit une surface incurvée par adjonction à la surface d'une lentille plan-convexe, et ce, par contact optique ou collage. Selon une autre réalisation, on a pu centrer une lentille astigmatique dans un bras du résonateur et l'incliner selon l'angle de pseudo-incidence brewstérienne par rapport à l'axe optique du résonateur. Selon une réalisation préférée, chaque prisme présente un angle sommital d'environ 135· moins l'angle de pseudo-incidence brewstérienne, un deuxième angle d'environ 90·, et un troisième angle d'environ 135· moins deux fois l'angle de pseudo-incidence brewstérienne.
